Two children from the underworld, Yagami [The White Tiger] and Sakura [The Jaguar], were seen as 'Odd' by their parents'. Due to them being from the Underworld, they expected them to be 'Big, Strong Demons' when they grew up, but the pair where too kind and nice, according to their relatives.

Without any other option, they went to Yasuhina [Ikura's brother and other Half of the Demon God] for help, only for him to defend the children's actions and seeing nothing wrong. Angered, the parents abandoned the children with Yasuhina. However with Hina and Ikura's Training, they grew into two strong yet respectable and kind demons. [The two Students of the Demon God.]
